This research aims at building the conceptual model and proposing concrete ways for raising the ICT productivity of the under-served groups. This research consists of four areas: 1) review and discussion of studies on digital divide issues, 2) theoretical reasoning of the relationship between informatization and productivity, 3) analysis of the present status of information gap between the under-served groups and the general public in Korea, finally 4) proposing the directions of policy making and various concrete ways for reducing information gap and raising the ICT productivity of the under-served groups through facilitating digital inclusion. The model of enhancing the ICT productivity of the under-served groups was theoretically reasoned to include three dimensions which are named as Economy, Efficiency and Effectiveness. The results of this research can be utilized for making policies of not only enlarging the digital opportunity of people in the under-served groups but also raising their income level and quality of life.

The traditional crop productivity simulations based on crop models are normally site-specific. To simulate regional crop productivity, the spatial crop model is developed in this study by integrating Geographical Information System (GIS) with Erosion Productivity Impact Calculator (EPIC) model. The integration applied a loose coupling approach. Data are exchanged using ASCII or binary data format between GIS and EPIC model without a common user interface. The spatial EPIC model is conducted to simulate the average corn and wheat productivity of 1980s in North China. The results show that the simulation accuracy of the spatial EPIC model is acceptable. The simulation accuracy can be improved by using the detailed crop management information, such as irrigation, fertilizer and tillage schedule.

Productivity has been a wide-ranging challenge for the construction industry, both in Australia and globally. Particularly in Western Australia's construction and resources sectors, continuously low productivity will potentially discourage future investments. The emergence of the global marketplace necessitates that the supply chain needs to focus on the concept of the holistic efficiency. The isolated geographical position of Australia only exacerbates this phenomenon. In recent years, Building Information Modelling (BIM) has been suggested as an efficient way to help productivity improve and information management throughout supply chains. This keynote talk will focus on discussing ways of implementing BIM to enhance site productivity focusing on Western Australia's construction projects. It will show new trends of its applications to accomplish an innovative way in construction project management. The talk will also give an insightful summary of integrated methods with state-of-the-art technologies backboned by the BIM cases from construction and oil and gas industry projects.

This study empirically analyzes the effect of IT SME ventures' external information network diversity on their production period reduction and productivity improvement generated from technology development. This research constructs a mediating model based on the open innovation perspective and tests it with the 138 samples of South Korean IT SME ventures based on the ordinary least squares regression. This research is expected to make a good contribution by shedding a new light on the following three points about the critical role of IT SME ventures' external information network diversity in increasing their production period reduction and productivity improvement generated from technology development which has scarcely been illuminated in the extant studies in the field of the management of technology for SMEs. First, IT SME ventures' external information network diversity positively influences their production period reduction. Second, the external information network diversity positively influences IT SMEs' ventures' productivity improvement. Third, IT SME ventures' production period reduction partially mediates the influence of IT SME ventures' external network diversity on their productivity improvement. These three fresh points are expected to provide useful theoretical and practical implications. Related to the theoretical implication, this research provides a fresh implication that IT SME ventures' external information network diversity positively influences not only their production period reduction but also productivity improvement generated from technology development. Concerning the practical implication, this study suggests that the CEOs in IT SME ventures make strategic efforts to use more diverse external information sources in order to increase their production period reduction and productivity improvement generated from technology development.

In general one can find an enormous number of studies about the productivity of land, labor and capital, very little has been done so far to communicate about the productivity of corporate information creating and information-consuming resources in ways that are useful to business executives. In view of the enormous share of corporate spending on information resources it would be useful in planning, budgeting, as well as in performance evaluation to measure how information resources are used in creating EVA(economic value-added). The effectiveness in deploying information resources has potentially a greater effect on corporate financial performance than any other economic influence. That in because corporate executives have greater discretion in directing what their information management staffs will do than in setting the terms for materials purchases, employee compensation, taxes or interest rates. The expenses for information are mostly in the form of overhead costs. Because expenses for information are mostly overhead costs and not for costs of goods, the prudent decision-maker should have a wide array of discretionary options available for allocating this resource. This study is intended for analysis the factors that having effects on the enterprise information productivity and is to description the factor using a foreign enterprise case study.

국내 건설산업에서 생산성 정보의 필요성과 그 활용에 대한 중요성 인식에도 불구하고, 현장 단위의 공사계획 시 효과적인 피드백을 통한 생산성 정보관리가 미흡한 실정이다. 공사계획의 신뢰성을 향상하기 위해서는 생산성 정보의 효과적인 활용이 요구되지만, 현장에서는 공사계획을 관리자의 경험 및 직관에 의존하고 있다. 생산성 정보가 효과적으로 관리되지 못하는 이유는 생산성 정보의 관리를 위한 추가 인력투입이 어렵다는 점, 기존의 생산성 정보가 새로운 프로젝트에 적용되기 어렵다는 점 등 때문인 것으로 파악되었다. 이러한 문제의 해결방안을 제시하기 위해서 선행연구조사 및 면담조사를 하였고 그 결과 새로운 시스템이 필요하다는 사실을 확인하였다. 새로운 시스템의 요구사항으로는 최소화된 업무, 한정된 정보관리범위, 정보의 분류, 정보의 피드백, 생산성 저하요인의 고려 등이 있다. 본 연구에서는 상기 내용을 바탕으로 생산성 저하요인 및 생산성 정보의 관리가 가능한 시스템의 프레임워크를 제안하였다. 이 시스템은 사용자 접근성이 좋은 SketchUp 소프트웨어를 활용하여 프로그램의 활용에 따른 추가인력의 투입이나 업무량 증가를 최소화할 수 있도록 하였다. 제안한 시스템은 준비단계, 입력단계, 처리단계, 출력단계의 총 네 단계의 과정을 통해서 정보를 입력하여 처리하고 출력하도록 하였다. 입력한 시공정보는 건축공사 표준시방서에 기재된 내용을 참고로 구성한 Task Breakdown Structure (TBS)와 Material Breakdown Structure (MBS)를 통해서 분류되어 생산성 정보로 변환되도록 하고, 변환된 정보를 그래픽으로 화면에 출력하도록 하여 사용자는 이를 활용해 해당 현장에서의 생산성 정보를 활용할 수 있도록 하였다. 본 연구에서 제안한 생산성 정보관리 시스템을 K 사옥 공사현장에 대입하여 현장적용 가능성 및 정보 활용성 측면에서 검증하였고, 사용성 및 적용 가능성에서 매우 긍정적인 결과와 정보 활용에 따른 이득이 있을 것으로 예상되었다. 본 시스템을 활용할 경우 생산성 정보를 활용한 공사계획이 가능할 것이고 추후 정보가 지속해서 누적될 경우, 본 연구의 기대효과는 더욱 높아질 것으로 사료된다.

Estimating the productivity of labor has relied on the experience and intuition of an estimator, or productivity data, such as standard in practical estimation. However, when new technologies and new construction methods employed in the construction industry, Dependence of a quantity surveyor's intuition is increased. This is because of the lack of a systematic methodology which models, estimates, and measures the labor productivity, Due to the historical productivity data is unavailable. Even thought project history data contains information that is important to predict the performance of a project, It can not provide valuable information to model, estimate, and measure the labor productivity. This is because 1) the absence of the productivity measurement system with consistency, 2) the difficulty of reusability of historical data collected. Therefor, this study suggests a methodology which build a productivity model by measuring the productivity of labor and collecting the historical data systematically. In addition, this methology is applied to develop a productivity model of shop-drawing and manufacturing process using descrete event simulation.
